FIRE- ALARM SIGNAL.

SPECIFICATION forming part of Letters Patent No. 335,027, dated January26, 1886.

Application filed April 18, 1885. Serial No. 162,718. (No model.)

To all whom it may concern.-

- Be it known that I, THOMAS F. GAYNOR, a resident of Lexington, in thecounty of Fayette and State of Kentucky, have invented certain new anduseful Improvements in Fire-Alarm Signals, of which the following is aspecification.

My invention relates to that class of firealarm-signal devices which isemployed to transmit or send out over one or more circuits any desirednumber or alarms by an apparatus which may be readily set in motion bythe operator by adjusting the index and starting the clock-work train toindicate any desired number or any given signal.

The object of this invention is to produce improved mechanism which canbe set in motion to automatically repeat any number of times any desiredsignal, and to send the same over one or more circuits, all of whichwill be fully set forth in the description of the accompanying drawings,making part of this specification, in which-- Figurel is a frontelevation of my improvement placed in a suitable box. Fig. 2 is anenlarged front elevation, with the outside cover of the box removed,partly in section. Fig. 3 is a detail sectional view of the settingmechanism. Fig. 4 is a diagram showing the circuit-connections. Fig. 5is a modification of the cirouit-breaking device. Fig. 6 is a plan Viewof the dial-plate.

A represents the frame-work of a suitable box,which is adapted to be setin any convenient position at the main station of a firealarm system.

a a or. represent dial-faces, which are numbered to the right fromnaught upward.

Within the box is placed a clock-work train consisting of a Windlass, 1,cordweight 2, and spur-gears 3 4 5 6.

7 represents an escapement, and 8 a weight which is adapted to beregulated upon the pendulum-rod 9 to control the speed of the revolvingdrum. 1

10 represents a tripping-arm which is mounted on shaft 11 of Windlass 1.The clock work train is set in motion by moving the tripping-arm 21, andit operates generally in 50 the manner shown and described in myapplication of November 18, 1884, Serial N 0.

148, 229. Shaft 13,which is driven by gear 4, carries a revolvingcylinder 14.

15 represents a gear keyed to said shaft, driving gear l6,which carriesa similar cylinder, 17. Additional cylinders and gears may be employed,as desired. Cylinder 14 is placed opposite dial a, and is provided atregularintervals, b, with teeth 0, which serve as circuitbreakers, asshown in section, Figs. 8 and 4.

The series of teeth shown in section indicate the number 32, and theseteeth are opposite the number 32, Fig. 6, of dial a, and. a number ofcircuit-breakers corresponding to the numerals are arranged along theface of the cylinder, so as to come opposite their proper numerals onthe dial plate. One or more spring circuit-breakers are employed, so asto be set in relation to any one of the numerals on the dials a a o tosend the alarm whenever the clock-train is in motion. This clock-trainoperates after the manner shown in my said former application, but thecontact-spring is made adjustable in the following preferred manner: Theeontact-spring C is mounted upon a sliding stock, B, 01 being aninsulator, dabinding-post. d aset-screw passing through the stock B forraising the rubber to adjust the tension of the spring-arm C.

D E represent guide plates or ears, which are attached to the shank ofstock B each side of the dial-plate a, which is provided with alongitudinal slot, inwhich the shank of stock B rests and slideslaterally.

6 represents an index-finger to aid in setting the mechanism.

F representsa handle attached to the shank of stock B, so that thedevice may be slid laterally in the slot 15 of the dial-plate a to bringthe contact-spring arm C into contact with the circuit-breakingprojections of any desired number on the cylinder 14. Cylinder 17, andeach additional cylinder, has similar metallic circuit breakingprotuberances, c, of numbers higher than those on cylinder 14, and it isprovided with a similar dial and circuit-breaking spring, C, attached tothe setting mechanism D F.

In order that the signaling mechanism may be employed to send thesignals over a differ- I00 ent number of circuits-as, for instance, toring one or more tower-bells, to ring an alarm at box A and in themain-battery circuit I,

by diagram, Fig. 4:. I representing the battallic connection with theopposite poles of the .as shown in Figs. 2, 3, 4, I have made a modi--inder provided with teeth m, wit-h which the the mayors oflice,station-house,water-works, or other different points which are indifferent circuit-conncctions--I have provided a multiplex armature, 18,'for relay H. The coils of the relay are connected in circuit with thecircuit-breaking cylinders, as represented tery of thesignaling-circuit, and J K L M representing batteries ofrepeating'circuits operated by the armature 18 of relay H; but thecircuit which is operated by cylinders and battery I may also be used tooperate bells and other signal mechanism as a main circuit.

ins t represent contact-points in metallic connection with the batteriesJ K L M.

0 '0 Z n represent contact-points mounted upon the armature 18 of therelay, and in mebatteries J K L M from that of the contactpoints z r st. When the battery I is closed by the contact of the teeth 0 with thespringarm 0, armature '18 is attracted by relay H, and batteries J K L Mare closed by the contact of points 0 '0 Z n with points i r s t, andthe signal by the revolving of the cylinder is repeated simultaneouslythrough all the circuits connected by the multiple armature of therelay.

I do not wish to limit myself to the number of circuits which may beconnected through the armature of the relay, as any desired number maybe employed.

20 represents a key placed outside of the which may be operated to closethe circuit when the cylinders are at rest, and telegraph communicationsthrough the circuits operated by the batteries J K L M, as well asthrough the circuit of the main battery I.

Instead of employing the teeth in cylinder,

fication (shown in Fig. 5) representing a cylcircuit-breaker C is incontact.

0 represents a rubber or insulator made to surround the cylinder,insulating the teeth from each other, so as to prevent accidentalcontact if the point of thecircuit-breaker is brought in contact withthe periphery of th cylinder.

The operation of the key 20 and of the clockwork train is similar inoperation to that shown in my said former application.

21 represents a spring-trigger for arresting and starting the movementof the trippingarm 10 and the clock-work train; or the clockwork trainmay be set in motion by means of a key operated in the manner describedin my application, Serial No. 148,230, filed November 18, 1884.

I claim 1. In combination with a clock-work train having an arm upon itsmain shaft, a pivoted spring'actuated lever engaging with said arm, aseries of cylinders, 14 17, driven by said train and having upon theirperipheries circuit-breaking teeth, spring-arms G, resting upon saidcylinders, and stocks'B, carrying the spring-arms and adjustablelongitudinally relatively to the cylinders, substantially as described.

2. In combination with a clock-work train,

one or more cylinders having upon their peripheries several separateseries of circuitbreaking teeth, each series being adapted to sound aseparate signal, a main battery in circuit-connection therewith, aspring-arm, C, to each cylinder, and adjustable longitudinally upon saidcylinders, and dials a, upon which said arms are adjusted, substantiallyas described.

3. In combination with a main battery, I, having circuit-connection withone or more circuit-breaking cylinders, a circuit-closing spring-armadjustable longitudinally upon said cylinders, a relay interposed insaid circuit, an armature having a series of contactpoints, each havingconnection with one pole of a separate battery, and a series ofcontactpoints in connection with the other pole of said battery,substantially as described.

In testimony whereof I have hereunto set my hand.

THOMAS F. GAYNOR.
